Outcomes and Prognostic Factors of Extensive Stage Small Cell Lung Cancer: A Retrospective Study.
Article in South Asian journal of cancer, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: Small cell lung cancer (SCLC) represents about 15% of all lung cancers. Extensive stage (ES) SCLC represents around 60% of diagnosed SCLC cancers. The median survival in untreated ES SCLC is 2 to 4 months and that of treated cases is 8 to 13 months. Aim and Objectives: This retrospective analysis aims to find out the clinical outcome of patients with ES SCLC and the prognostic factors affecting their survival. Methods: Details of patients registered in the department of radiation oncology from January 1, 2010 to September 30, 2019 were retrieved from the hospital records. This includes the demographic characteristics, treatment received, toxicity, and follow-up details. Results: Two-hundred eighty-three patients were included. Median age of presentation was 62 years. Around 97.5% of patients were men. Smokers constitute 94% of all cases. About 86.9% (246 patients) of cases were not alive at the end of the study period. The median estimated overall survival (OS) was 7 months ± 0.47 (95% confidence interval [CI]: 6.026-7.974) and progression-free survival (PFS) was 5 months ± 0.535 (95% CI: 3.952-6.048). Multivariate analysis showed that Eastern Cooperative Oncology Group performance status (ECOG PS), hyponatremia, number of chemotherapy cycles, consolidative radiotherapy (RT) and prophylactic cranial irradiation (PCI) were found to have prognostic effect on OS. Smoking, ECOG PS, number of chemotherapy cycles, consolidative RT, and PCI were found to have prognostic effects on PFS. Conclusion: There is a difference in OS and PFS patterns of ES SCLC patients among various Indian studies even though the available data is scarce. Our study shows that the OS and PFS of our study population are comparable to other South Indian studies available. PS, serum sodium level, number of chemotherapy cycles, consolidative RT, and PCI were found to be independent prognostic factors for survival of ES SCLC. The identification of these factors will help physicians to tailor treatment.
